mark – [OLD FALL 2020] 15-104 • Introduction to Computing for Creative Practice

Final Project

Fri, 11 Dec 2020 21:18:08 +0000

For this final project, I wanted to create a drawing program for users. I wanted to create a platform that inspired users to be creative for themselves. In 2020, practicing my creative interest was a great way for me to keep my mind off of the current social climate, and focus on something that I enjoyed doing – I wanted others to experience that. It is a simple program, but it works, and it is enjoyable. Just run the program, and start drawing!

If I had more time, I would have added stroke features and visuals that effectively guide the user through choosing color and stroke. And perhaps a randomly generating image relating to 2020 asking users to copy the image.

sketch


var strokeColor;
var hover;
 
function setup() {
    createCanvas(600, 600);
    strokeColor = color(0);
}
 
function draw() {
    
    noStroke();
    fill(0);
    //borders
    rect(0, 0, width, 80);
    rect(0, height - 20, width, 50);
    rect(0, 0, 20, height);
    rect(width - 20, 0, 20, height);
    //text color
    fill(255);
    textSize(10);
    text("Press the circle button to change the color", 20, 55);
    text("Press Q to clear canvas", 20, 70);
    //title
    strokeWeight(5);
    textSize(15);
    text("Draw your favorite moment from 2020!", 20, 30);


    stroke(strokeColor);
    //calculating distance between mouse and circle
    var distance = dist(mouseX, mouseY, 540, 120); 
    //making sure disatnce is less than circle's radius
    if(distance < 15) {
        hover = true;
    } else {
        hover = false;
    }

    push();
    //draw a circle

    ellipse(540, 120, 30, 30);
    pop();

    //testing is mouse is over the circle

Project 11 – Generative Landscape

Sat, 14 Nov 2020 01:52:47 +0000

For this project, I wanted to create a simple winter landscape, because Christmas is coming and it’s quite exciting. Take a close look at this landscape and close your eyes and imagine that you are Santa Claus on a nice warm sled on your way to California.

I used the noise function to generate the mountains, and objects to create snowflakes and buildings.

var buildings = [];
var mountains = [];
var noiseParam = 0;
var noiseStep = 0.03;
let snowflakes = [];


function setup() {
    createCanvas(400, 240); 
    
    for(var i = 0; i < width/5; i++){
        var n = noise(noiseParam);
        mountains[i];
        var value = map(n, 0, 1, 0, height);
        mountains.push(value);
        noiseParam += noiseStep;
    }
    // create an initial collection of buildings
    for (var i = 0; i < 10; i++){
        var rx = random(width);
        buildings[i] = makeBuilding(rx);
    }
    frameRate(25);
}


function draw() {
    background(23, 39, 174);

    cloud(40, 47, 1);
    cloud(275, 15, 0.8);
    cloud(380, 70, 1.5);

    let t = frameCount / 20; // update time

     // create a random number of snowflakes each frame
  for (let i = 0; i < random(5); i++) {
    snowflakes.push(new snowflake()); // append snowflake object
  }

  // loop through snowflakes with a for..of loop
  for (let flake of snowflakes) {
    flake.update(t); // update snowflake position
    flake.display(); // draw snowflake
  }
}

// snowflake class
function snowflake() {
  // initialize coordinates
  this.posX = 0;
  this.posY = random(-50, 0);
  this.initialangle = random(0, 2 * PI);
  this.size = random(2, 5);

  // radius of snowflake spiral
  // chosen so the snowflakes are uniformly spread out in area
  this.radius = sqrt(random(pow(width / 2, 2)));

  this.update = function(time) {
    // x position follows a circle

      snowflakes.splice(index, 1);
    }
  };

  this.display = function() {

    //for animating the mountains
    mountains.shift();
    var n = noise(noiseParam);
    var value = map(n, 0, 1, 0, height);
    mountains.push(value);

Reality Reduction

Lorna Barnshaw

Reality Reduction

For this Looking Outwards post, I will be talking about Lorna Barnshaw’s project called Reality Reduction (2013). Lorna Barnshaw is a 3D designer from London, United Kingdom, with a bachelor’s degree of Fine Arts from Winchester School Of Art. She works as a freelance designer, creating 3D designs during her free time. Her project, Reality Reduction consists of random people 3D scanned in 360 views and using computation to reduce their features to low-poly shapes. She simplifies the person’s features and pixels to visualize what a person may look like after reduction. This project is really interesting to me because it uses advanced technology to effectively communicate her concept. It is both eerie and interesting at the same time, captivating the viewer by its realistic scans.

Project 10 – Sonic Story

Sun, 08 Nov 2020 19:35:35 +0000

For my project, I created a story of Santa Clause delivering presents and running into a penguin. Now that Halloween is over, it is Christmas time.

Cymatics

Nigel Stanford

Nigel Stanford

For my Looking Outwards post, I will be talking about a sound visualization project done by Nigel Stanford. For his latest music video for Cymatics, Stanford decided to use various methods of visualizing sound through natural materials, demonstrating how sound waves affect different types of matter. He uses instruments and computation to effectively convert the sound to waves that can be demonstrated physically. I admire this project because the main focus was creating the visuals of sound: “I looked for interesting science experiments that showed how sound waves affect things, figured out what looked good, and then wrote the musical parts for each experiment” (Stanford). Not only is he using his creativity for his music, but also pushes himself to visualize sound, which allows for a whole new experience for the viewer.

Bone Chair (2006)

Joris Laarman

Bone Chair (2006)

For this looking outwards post, I took a look at Jubbies’ post on Generative Art regarding Joris Laarman’s Bone Chair. In reading her response to Laarman’s work, I agree with what she said – As a design student myself, I find meaning and great appreciation for beautiful things, but something that embodies both form and function. As stated in her post, Laarman uses algorithms to mimic the natural growth of bones and trees to create a chair that has the most minimal structure to support the human body. I found this very intriguing because this piece represents the patterns of nature through a physical object that we interact with on a daily basis, yet still considering the form and function of the said object. From afar, this piece may seem like a “cool” surface level chair but the process of discovery and learning is required thus appreciating the chair even more.

Project 9 – Computational Portrait

Sat, 31 Oct 2020 20:54:15 +0000

For this project, I wanted to create Van Gogh’s self portrait with the text “Van Gogh.” By using custom pixels, I was able to make words appear on the canvas in relation to the pixel color of the original image. Wait a little bit to view the full portrait!

sketch

let img;

function preload() {
  //preloading the van gogh image
  img = loadImage("https://i.imgur.com/wUgkJwF.jpg");
}


function setup() {

  background(0);
  img.loadPixels();

}

function draw() {
  //coverage of the words on the canvas
  let randomWords = random(0, 400);
  let randomWordstwo = random(0, 300);
  //placement of words in relation to the image width and height
  let x = floor(random(img.width));
  let y = floor(random(img.height));
  //pixel and text relationship
  let pixel = img.get(x, y);

YOUR OWN MULTIVERSE

Meow Wolf

I watched the Vimeo video about Meow Wolf, where they talk about reasons why they succeeded, and the early history of Meow Wolf as an art collective. Meow Wolf is an arts and entertainment group based in Santa Fe, New Mexico. They established in 2008 as an art collective with a special emphasis on the DIY technological aspects of immersive art. I admire this group because of their work (obviously) but also their mission statement. They believe in accomplishing artists being compensated on an equal level with other skilled, in-demand professionals (a societal issue that is very prominent today) and that successful businesses must give back and participate in their communities. As an art collective, not only do they create mesmerizing user experiences, but also provide financial assistance, expertise, and other forms of active support. Meow Wolf captivates the audience by introducing their mission through anecdote and humor adding levity to the expo.

PENNY

By Stamen Design

PENNY Wealth distribution analysis on satellite map

Today, I will be talking about an AI Project called Penny done by Stamen Design. This simple tool is designed to help understand what wealth and poverty look like to a artificial intelligence built on machine learning using neural networks. Penny is built using income data from the U.S. Census Bureau, overlaid on DigitalGlobe satellite imagery. This information was then given to a neural network. Trained to predict the average household incomes in any area in the city using data from the census and the satellite. The AI looks for patterns in the imagery that correlate with the census data, and over time, users are able to ask the model what it thinks income levels are for a place just from a satellite image. This project is really interesting to me because this visualization and AI can be used to improve the quality of life, and physically see the imbalances within a neighborhood for better wealth distribution.

Project 7 — Composition with Curves

Fri, 16 Oct 2020 06:01:34 +0000

For this project, I wanted to draw a single object but in different ways. I took the functions from the website provided in the project brief and decided to draw a heart by plugging in functions for “x” and “y” and using the “beginShape()” function. I first began by using a “for loop” to draw a circle by creating a local variable that adds in increments for every loop. By altering this variable, I was able to draw the heart in different ways.

function setup() {
    createCanvas(400, 480);
    background(220);
    text("p5.js vers 0.9.0 test.", 10, 15);
}

function draw() {
    background(0);
    translate(width / 2, height / 2);

    //heart one
    push();
    translate(-100, -130);
    noFill();
    strokeWeight(0.5);
    stroke(255);
    beginShape();
    for(var a = 0; a < TWO_PI; a += 0.3) { //this function draws a circle before the equation is put in
        if(mouseIsPressed){
            stroke(random(255), random(255), random(255)); //color change
        }
        //drawing the first heart
        var r = constrain(mouseX / 180, 1, 70); //movement of mouse
        var x = r * 16 * pow(sin(a), 3);
